Carbon nano-onions (CNOs), a form of carbon nanostructure with excellent electrical and thermal conductivities, find several applications in biomedicine, bioimaging, energy conversion, and electronics. However, conventional methods to produce them suffer from high complexity, toxicity, and energy consumption. Fortunately, scientists have now found a convenient and eco-friendly way to synthesize high-quality CNOs using scales from fish waste and microwave pulses. This novel approach could open doors to the adoption of CNOs in next-generation technologies.

Thanks to their low toxicity, chemical stability, and remarkable electrical and optical properties, carbon-based nanomaterials are finding more and … Read More → "Turning Fish Waste into Quality Carbon-based Nanomaterial"
